Weak bones and falls are a major public health concern, but much can be done to prevent them.

Bone health is a bit like saving for your pension: hard to get excited about when you're young but the sooner you start, the better.

Taking care of your bones is a lifelong investment that will pay dividends by helping you to stay fit and independent later in life.

Like pensions, it's never too late to start. There's plenty you can do to keep your bones fit for purpose, whatever your age.

Let's be clear: bone health isn't just about bones. "It's about your quality of life as you get older," says Ruthe Isden of charity Age UK.

"Bone health is about staying fit and well as we get older so we can continue to do the things we enjoy," she says.

As we live longer, more and more of us will become vulnerable to weak bones (osteoporosis) and breaking bones from falls.

Life-changing fracture

About one in three people over 65, and half of people over 80, fall each year in the UK. One in two women, and one in five men over 50, will break a bone, typically in the wrist, hip and spine, as a result of osteoporosis.

A fall later in life can be life-changing, leading to distress, pain, injury, loss of confidence, loss of independence and even death.

Half of older people never regain their former level of function after a hip fracture and one in five dies within three months.

According to a blog by Professor Kevin Fenton, Public Health England's national director for health and wellbeing, "Falls are the number one precipitating factor for a person losing independence and going into long-term care,".

What you can do

But it doesn't have to be this way, says leading bone and joint expert Professor Anthony Woolf, a rheumatologist at the Royal Cornwall Hospitals NHS Trust. "Osteoporosis and falls are not an inevitable part of ageing and much can be done to prevent them," he says.

Preventing osteoporosis starts in childhood, if not earlier, when our bones are growing, and continues throughout life. "Building healthy bones actually starts in the womb where the baby's skeleton is developing," says Professor Woolf. "A real life course approach is needed to help people have bones fit for purpose as they age."

Bone-building years

The key bone-building years are those up to our mid-20s, when the skeleton is growing. For example, the bone accumulated in girls aged 11 to 13 is about the same amount lost during the 30 years following the menopause. Research has shown that gymnasts aged 10 have much stronger bones than inactive youngsters of the same age.

The gains achieved during youth put the skeleton in a better position to withstand the bone loss that occurs with age. Get tips on boosting your child's bone health. After about 35, bone loss gradually increases as part of the natural ageing process.
